" t 4 Claims. (01. 21s s3) o 2 pens'er comprisesa casing, preferably, formed by two half body portions I and 2 which are central- 1y 'joined at '3. Located centrally of the casing. is a hollow spindle 4 upon which is mounted a roll'of pressure sensitive tape 5. Thespindle 4 comprises parts of the body members l and 2. A secondIspindle-B, forming part of the body portion 2, has the loose end'l of the tape trained thereabout best illustrated in Figure 1. This spindle may or may not have a revolving sleeve,

This invention relates to a tape applier and dispenser and is particularly related to-pressu're sensitive tapes. I, r

The pressure sensitive tapes that-areto be I dispensed with my dispenser are those tapes hav- 5 ing an adhesive material applied to oneside, said adhesive requiring no further treatment when applying than to press the same against 'an object. Usually this tape is of transparent material, the adhesive being applied to the tape at its origin and ready to apply when the tape is 8 therearound. removed from the roll. The tape 1 passes through the channel 9 and The primary object of the invention is to proout through the opening III which is defined by vide an applying device that will press the tape the lower end of the upwardly and forwardly directly to the object to which thetape is being l5 curved front or applicator wall and the forward applied, causing the tape to adhere thereto inupwardly curved end of the bottom or outer wall stantly. of the casing. The tape passes upwardly in front A further object of the invention is theproof the applicator. wall which" carries a pressure vision of a tape applying device that will commember, specifically a, resilient pad II the adpletely apply the tape to 'a receiving surface and hesive side of the tape facing outward or away also having a provision associated therewith for. from the pressure plate. The tape, when out, tearing the tape off, and at the s ame time posi recoils due to its natural elasticity, and, in re tioning the exposed ends of the tape relative to coiling toward the spindle 6, engages the inner the dispenser ready for the next application, all e j surface I2 of the cylindrical portion I3 forming accomplished without contacting the tape with 25 the forward, end of the bottom wall of the device. the fingers of the operator. g v The tape adheres to the surface l2 and thereby Another object of the invention is to; provide prevents the tape from rewinding into the case means of doubling the tape back on the device when not being applied. v for storage until it is required to dispense the Due-to thefact that the spindle p 6 is located tape and apply the same to a desired object.

These and other-incidental objects will be 'apparent in the drawings, specificationand claims.

Referring to the drawings:

Figure 4 is a fragmentary enlarged sectional view taken on line 44 Figure 1, illustrating the tape roller within the case of the device.

Figure 5 illustrates the relative position of the tape applier and dispenser while applying tape to an object.

Figure 6 illustrates the tearing off of the tape and the relative position of the hand of the operator while holding the dispenser.

In the drawings:

atl5 against the edge l2 of the body of the devicea'fter an application of tapehas been made and torn off from the end [6. The resilient pressure plate' l is cemented to the body of the devicea I will now describethe operation of rny" new and improved} tape applying and dispensing dea vice. "ReferringtoFigures'5' and 6', the end 16 of the tape 1 is applied to the object It at H) by r ."applying the pressure plate I! against the surface of the s ame, which presses the end of the tape I6 against the object I8, then the device'is pulled towards the operator or away from the object.

When it is desired to sever the tape, the device being held in the hand 20 of the operator, is

ertravelling over I i has, been applied to thegtape is causes the tape' tilted away and out from the object, as best illustrated in Figure 6, at the same time twisting slightly sidewise causing the cutter blade 2| to tear the tape at 22. As the tape is being applied to the surface of the object, it is also being stretched between the spindle 6 and the ends l6 "and; a uthe-tape rolls around ,the spindle 6,

move towards the pressure plate. This movement towards the plate'l l is assisted by the outward tension of the tape at 15 against the edge" H of the case, which maintains-the end of the. tape [6 againstthe pressure plate H 56 that it will be ready to apply against the object to be taped. M

It will be noted in Figure 1 that there a general bow imparted to the tape due to its the spindle 6. Afterthis .bow

. to ear against the pirit ,l5;as abovefdescribed which provides a leverage between" the spindle 6 and the point it, and as above describedcauses' the end [6 to move towards'th pressure plate.

s This action. is alsoass'isted by the fat that when" ,..the tape is severed, a tensionis applied-to the tape byjthe action'of the pull of the device be-"" tween the spindle 6 and the end- I5, stret*hing' the tape. However, the instant the tape is sever'ed,;it then tends to contract, striking at the point lezagainst the edge [2 and adhering to a casing having a fixed upwardly and forwardly" projecting applicator wall extending to a terj minus, a bottom wall having its forward end curved upwardly and spaced from the applicator? wall to form a tape passage therebetween and-- terminating short of the terminus of saidapT nplicator wall, a support in the casing for a coiled" it is .curled inwardcso that the end [6 tends to r inner tape, a tape roller,jguide 'in1the casing at the 'end of the passageand' around which the tape is drawn to form a reverse bend to create a bow in the tape, and a cutter at the terminus oithe applicator wall to sever the tape.
